TRANI, P.E.; HAAG, H.P.; DECHEN, A.R. and CATANI, C.B.. Concentration of nutrients in the apple fruits at different ages. An. Esc. Super. Agric. Luiz de Queiroz [online]. 1981, vol.38, n.1, pp.435-464. ISSN 0071-1276. http://dx.doi.org/10.1590/S0071-12761981000100036.
On an apple grove situated at Buri, State of São Paulo, fruits were collected from trees 1-2; 3-4; 4-5, and 6 - 7 years old. The fruits were analysed for N, P, K, Ca, Mg, S, B, Cu, Fe, Mn and Zn. The authors concluded: a) the concentrations of the nutrients in the fruits differ according to the variety, age of the tree and age of the fruit; b) the concentrations of nutrients decrease with aging of the fruits; c) the concentrations of the macronutrients obey the following order: N>K>P>Ca>S> Mg; d) for the micronutrients, the following order was ob -served: Fe > B > Mn > Cu > Zn.
